Hello Gabriela:

Your question is about the translation to Spanish of the term “jaw” on the context: “MLC FIT: INCORRECT JAW POSITIONS”

ANALYSIS

MOSAIQ is a software for the processing of 3D images of the body and it is reasonable that takes images of different parts of the body: pelvis, prostate, jaw

BILINGUAL VOCABULARY (related to the context)

1) English term “jaw” = in Spanish “mandíbula” (en una persona) , “quijada” (animal)

TRANSLATION

The translation of “incorrect jaw positions” to Spanish is: “posiciones incorrectas de la mandíbula”.

MY PROPOSAL:

- “mandíbula”

I hope this analysis helps you in your work.

Regards

Domingo

Hello Gabriela,

After you offered additional context about the expression “MLC FIT: INCORRECT JAW POSITIONS”, I made a new research visiting different web pages of manufacturers of MLC systems and reading also other documents.

In particular this paragraph of the new material gave me a different perspective of the subject: “Creating the MLC leaf plan (specifies leaf, jaw, collimator, and gantry position information) - MLC Fit uses color to clearly indicate the defined treatment area, leaves, jaws, and any exposed area or regions of overlap, then numerically displays all the critical information and controls you need to adjust the fit. Individual leaf and jaw positions can be edited manually with the mouse or keyboard, or all the leaves can be automatically positioned using the flexible fit features.”
(MOSAIQ User’s Guide, MOSAIQ Version 2.0. PDF document)

Thanks the previous reading, I learned the “jaw” that we are talking is a element of the MLC systems (“multileaf collimators”).

About the Multileaf Collimator, Wikipedia in English shows pictures when you write: “Multileaf_collimator”
URL: http://en.wikipedia.org/wiki/Multileaf_collimator. And Wikipedia in Spanish also shows pictures when you write: “Colimador”
URL: http://es.wikipedia.org/wiki/Colimador

The Multileaf Collimator (In Spanish: “colimador multiláminas o de múltiples laminas) is a tool for radiation therapy dose delivery. It is produced by different manufacturers: Elekta, Varian, Siemens, GE and others. All the makers produce systems with some common design features. Among these features, we find two “jaws” (mandíbulas).

The “jaw” (mandíbula) is a component of the MLC manufactured with tungsten, a chemical element that has excellent corrosion resistance and helps to reduce the radiations produced the multileaf collimators.

The “upper jaw” (mandíbula superior) forms the field in the Y direction.

The “lower jaw” (mandíbula inferior) forms the field in the X direction.

My proposal: “Ajuste del MLC: posiciones incorrectas de las mandíbulas (jaws)”

I hope this new analysis helps you in your work.

Regards

Domingo
